Adds a production-grade in-app version check that prompts users to update when a new build is available. Soft updates are dismissable. Force updates block the app entirely. Configured via FirebaseRemote Config so rollouts can be triggered without redeploying.
- Sealed result types (NoUpdate / SoftUpdate / ForceUpdate) for type-safe pattern matching
- AppVersionCheckService
- AppUpdateGate widget encapsulates listener, route guard and dialog wireup, isolated from save_family_app
- Serialized notifier operations prevent race between dismiss and refresh, mounted checks blindar disposal edge cases - Build-aware dismiss persistence via SharedPreferences
- Lazy-init sfTracking to avoid touching Firebase at import time
- DRY SfTrackingRepository with a single _broadcast helper
- Drop empty DashboardTracking, fix double step_completed in device_setup
- Move yearsBetween to packages/utils
- Add 5 unit tests for SfTrackingRepository
- Strip noisy comments from mixins and view models
Introduces packages/sf_tracking — a multi-client, GDPR-first analytics layer with feature mixins, a GoRouter listener for automatic screen views, and a user properties helper that runs on login.
Wires the package into the legacy module 61 events
